what is typeof((c) + 1) in C

Question

I came across an expression in C like

typeof((c) + 1) _tmp = c;

What exactly does this mean?

Thanks for the reply.

It is not standard C. C has no such thing as typeof (unless you are dealing with something user-defined).

typeof is normally a compiler extension (GCC compiler most likely). You can read about it here
